Local know-how

What Oak Lawn homes are up against.

Oak Lawn went from 8,751 residents in 1950 to 60,305 in 1970, as returning veterans used the G.I. Bill to buy homes. Most of the houses from that boom are still standing.

  • Sewer lines from the boom years

    A house from the '50s or '60s has a sewer line 60 or more years old. The Village of Oak Lawn runs a 50/50 cost-share program for private sewer repairs on older homes; call Public Works about eligibility. When a line backs up, our plumbers clear it with drain cleaning.

  • Furnaces in older houses

    Half of Oak Lawn's homes are 55 years old or more. If the furnace in yours is more than 10 years old, it may be nearing end of life, and a furnace tune-up will tell you whether to plan for a replacement.

  • Cooling a mid-century home

    Many houses from the '50s and '60s got central air after they were built, so today's system may be working with ductwork that wasn't planned for it. A central AC typically lasts 12 to 15 years. We repair what's worth fixing and size replacements to the house.

  • What's in the pipes

    Oak Lawn buys treated Lake Michigan water and keeps a service line material inventory you can request from the village. Inside the house, a reverse-osmosis filter removes contaminants such as lead at the kitchen tap.
